PATENT OFFICE- PANY INCL, OF NOR-TH TONAWANDA, NEW YORK, A CORPORATIONOF N EW YORK A PPAnATusroR .DRAINING BUNDLES or SHINGLES AND .THE LIKEApplication filed November 26, 1928. Serial No. 321,853. I

This invention relates to an apparatus for draining bundles of shingleswhich have been dipped in a bath of liquid, such as a liquid stain,paint or preservative, for. the purpose of removing the excess liquidtherefrom before the bundles of shingles are used or put on. the market,and thereby facilitate drying of the shingles as well as saving theexcess liquid for use in treating subsequent bunm dles.

d An apparatus of this character is shown in application for UnitedStates patent, filed May 3, 1928, Ser. No. 278,783. The presentinvention is an improvement on this prior construction.

In the use of this earlier apparatus it is found that when starting andstopping the rotary movement of the cage,freel or skeleton drum inwhichthe bundles of shingles were whirled so as to remove the excessliquid therefrom by centrifugal action, :during the beginning of thisrotary actioneand also during the last part of this rotary action aftercompleting the draining of the bundles, the

latter tended to chuck excessively from one side of the rotary cage ordrum to the other, thereby not onlysetting up an unnecessary vibrationand strain upon the machine, but also causing the two tiers of shinglesat opposo site ends of the bundles to be driven toward each otherexcessively with a hammering or pounding action and thereby at timescause the binder around the waist or central part of the bundles to bebroken so that the shingles would be scattered or spilled. v

This chucking action of the bundles within the rotary cage or drumdoesnot occur .during the intermediate part of the rotary action of thesame while it is running at full speed inasmuch as at this timecentrifugal force is suificiently strong to hold the bundles firmlyagainst one side of the cage instead of permitting them to chuck fromone side of the cage to the other, which takes place only during thebeginning andstopping of the operation While rotating at comparativelyslow speed.

It is the object of this invention to provide simple and efficient meanswhereby the bundles of shingles Within the rotary cage may beconveniently fastened or held against displacement within the cagesothat chucking of the bundles may be prevented, particularly at the timeof beginning and ending of the draining operation when this isnecessary.

In the accompanying drawings Figure 1 is a vertical longitudinal sectionof a satisfactory form of my invention embodied in a draining apparatus.1

Figure 2 is a side elevation of the apparatus with the enclosing hood orcasing removed from the cage so as to expose the latter.

- Figure 3 is a vertical section, on an enlarged scale, of the valvemechanism and adjacent parts of the motor whereby the clamping jaw isshifted and showing this valve mechanism in a position different fromthat represented in Fig. 1.

Figure 4 is a longitudinal section taken on line 4; 1 Fig. 3.

' Similar characters of reference indicate like parts in the severalfigures of the drawings.

The draining apparatus itself may be variously constructed to suit theparticular form of bundles of shingles or other materials which are tobe drained of their excessive liquid which may adhere thereto after thesame have been dipped or otherwisecoated, but the apparatus which isshown in the drawings as an example, consists generally of a rotary'cage, reel or skeleton drum which turns about a horizontal axis. Asthere shown, this cage comprises two vertical heads 1011 arranged atopposite ends of the cage, two longitudinal closed Walls which arearranged on diametrically opposite sides of the axis of-the cage andeach consisting of a plurality of longitudinal spaced-apart bars 12which connect the corresponding edges of the two heads 10, 1l, and twoopen-work gates 13, 13 which are arranged on diametrically oppositesides of the cage but in planes at right angles to the walls formed bythe fixed bars 12, 12, each of said gatesbeing movable horizontally intoand out of its, operative position across one side of the cage for thepurpose of permitting the bundles of shin-- gles. 14 which have beendipped in liquid stain, paint or the like, to be introduced into cagepreparator to draining the excess liquid therefrom an also to be removedfrom this cage after the draining operation has been completed.

A notary cage is thus formed which is substantigllysquarewij rectangularin cross section and into the interior of this cage the bundles 14 to bedrained are placed with the m Wuntereahteotiere of shingles-facing thebarslfl of the (age while the binder 15 around the central parts pfthese bundles are arranged near theaxisiif the cage. The diameter of thecage between the two walls formed 15 by the two sets of walls 12 is lessthan the length of the. ,bundles when the latter are put into the cage,so that when the bundles rest at. one end on the bottomof' the cage-theopposite ends thereof 30 arespaced apart from; the companion longitudinal top wall, as shown in Fig. 1. I

For convenienoein introducing the bundles into the cage and removing thesame therefrom, a plurality of rollers 16 are arranged as on the innersideofthe cage lengthwise of thetwo sets of bars,12 so that either ofthese twqsets of rollers may form a support for the ends of the bundles:which are lowermost thereby permit them; to be readily moved sointer-and out of the cage.

' 'mElGh of the heads 10 and 11 preferably consists of a central hub 17,a plate 18 arranged onthe inner side of this hub, and a plurality ofcross bars 19 secured to this hub .36 and plate and also to the adjacentends of the longitudinal bars 12 forming the respective longitudinalwalls of the cage. The plate 18 of one of the heads ispreferably made imrforate as shown at the right of Fig. 1, w ich an plfl wvillbehereafterreferred to as the front plate, while the other plate 18 isprovided with a central opening 20 and will be hereafter referred to asthe rear plate. The hub 17 of the front head is provided as with tanoutwardly projecting trunnion 21 .whiehis journaled inabearing 22 formedat thzaupper end of a standard 23 rising from ,theibasc 24 of themainframe, this trunnion preferably so that in effect it .50 f a part ofthe driving shaft 25 of the machineywhich latter is additionallyjournaled-at its outer endj'na bearing 26 rising from a standartl27 on;the main frame. The hub onthe rear head of the cage is provided 55withan outwardly extending trunnion 28 which. is axially in line withthe front trunnion 21 and journaled in a bearing 29 at the upper end ofa standard 30 rising from the base24 of the frame.

6c .Motion is transmitted to the cage for rotatingthe same by means 'ofa belt 31 passing around a driving 'ulley 32 on the shaft 25, oranyother suitalilemeans and this rotary monementof. the cagema becontrolled and fllfiflgfl may be also]; d. against rotation while beingloaded and unloaded by a retaining device which preferably consists of abrake drum 33 mounted on the driving shaft, and a brake band 34 whichmay be either tightened or loosened relative to the periphery of thebrake drum 33 by means of a hand lever 35 or any other suitable means.

As the cage or skeleton reel which contains the bundles is rotated theexcess liquid is thrown off from these bundles by centrifugal force anddischarged through the openings between the openwork sides of the cageinto a suitable receptacle provided for this purpose. The meansprovidedfor this purpose consist of a pan 36 arranged below the cage and avertically movable hood or casing 37 adapted to enclose the top, lateralsides and ends of the cage so as to catch the excess liquid which isthrown off from the bundles and direct the same into the pan 36, fromwhich latter this liquid is conducted into the tank where the same isutilized fordipping further bundles which are to be treated.

In the absence of any provision to prevent it, the bundles if left loosewithin the cage, would, during the initial partof the rotary movement ofthe cage and also the final portion of this movement when the drainageis completed, move back and forth crosswise of the cage with a chuckingaction due to the comparatively slow rotary motion of the cage at thistime.

This chucking effect upon the bundles is obectionable inasmuch as itdrives the shingles inwardly from their outer ends'so that the innerends thereof overlap to a. greater extent and therefore are liable tosplit the binders which hold the bundles together at the waist due tothe wedging effect of the shingles. After the cage has acquired itsnormal or maximum rotary speed centrifugal force opcrates to hold thebundles in their outermost radial position against one wall of the ca eso that this chucking action of the bund es does not occur at this time.In order to prevent chucking of the bundles during the initial and finalportions of rotation of the cage, means are provided for holding thebundles against displacement during these periods, which means, as shownin the drawings, are preferablyconstructed as follows:

The numeral 37 represents a clamping jaw which preferably has the formof a disk and is adapted to engage with the rear side of the rearmostbundle of a group arranged within the cage while the front side of theforemost bundle of this group is engaging with the plate 18 of the fronthead of the cage. This jaw 37 is movable into and out of the cagethrough the opening 20 in the plate 18 of the rear head so that this jawmay be withdrawn from the interior of the cage and permit freeintroduction of the bundles into the cage and removal therefrom. Asshown by full lines Hill dle while the clamping mechanism is inoperation.

This clamping jaw is moved into and out of its operative position bymeans of a pis ton 38 which reciprocates in a cylinder 39 formed in theouter end of the rear trunnion 28, and a piston rod 40 which connectsthis piston and the clamping jaw 37 and slides axially through the innerpart of the trunnion 28, as shown in Fig. 1. V

The piston 38 is pushed inwardly by compressed air or other fluid so asto engage the clamping jaw 37 with the rear end of the series of bundlesto be drained, and the outward movement of this piston is efiected bythe suction of a vacuum apparatus.

The means whereby fluid under pressure is admitted into the outer end ofthe cylinder 39 for forcing the piston inwardly and also exhausting theair from the outer end of this cylinder for causing the piston to bemoved outwardly and the clamping jaw to be disengaged from the shingles,are preferably construc'ted as follows l The numeral 41 represents acommunicating pipe through which the compressed air is supplied to theouter end of the cylinder and the spent air is exhausted therefrom,which transfer pipe is stationary but connected with the outer end ofthe cylinder 39 by means of a rotary pipe coupling so as to permitthecage to turn and still maintain a connect-ion at all times between theouter end of the motor cylinder 39 and the means which connect the samewith the pressure supply and the exhaust devices. This rotary couplingmay be variously organized, but as shown in Figs. 1 and 3, the samecomprises a central coupling nipple 42 extending axially through thehead 43 Secured to the outer end of the cylinder 39, and a stuffing box44 whereby an air-tight joint is formed between this head 43 andthecoupling nipple 42, the latter being provided at its inner end with acollar 45 which engages with the inner side of the head 43. 7

By these means compressed air may be admitted to the outer end of thecylinder 39 for pushing the cylinder inwardly and engag-ingthe clampingjaw with the bundles of shingles and upon exhausting this air the pistonis moved outwardly and the clamping jaw is released from the bundles ofshingles. Inasmuch as the clamping of the bundles of shingles so as toguard against chucking of the same is only necessary during the initialpart of the rotary movement and also the final part of this rotarymovement of the cage, means are provided which will permit the attendantto put the clamping mechanism in operation manually but which willoperate automatically to release the clamping or holding means from thebundles after a comparatively short time, and thereby permit the bundlesof s iingles to assume a definite position under centrifugal action within the draining cage and retain this posit-ion without further changeduring the operation of draining the same.

The preferred form of mechanism for thus manually clamping the bundlesof shingles and then automatically releasing the same is eflected by atimed or slow-acting release device which is preferably constructed asfollows The numeral 46 represents a valve casing provided with acylindrical bore 47 forming the valve seat of a cylinder or plungervalve 48 which is adapted to slide lengthwise in this seat 47. Ondiametrically opposite sides of the inner part of the casing 46 the sameis provided with inlet and outlet pressure ports 49, 50. The centralpart of this casing is provided on opposite sides with inlet and outletvent ports 51, 52 and on the upper part of this casing the same isprovided on opposite sides with inlet and outlet exhaust ports 53, 54.The outlet ports 50, 52 and inlet port 53 communicate by a communieatingchamber 55 with the pipe 41, the inlet pressure port 49 is connected bymeans of a pipe 56 with an air compressor or other means for supplyingfluid pressure, the inlet vent port 51 leads to the atmosphere and theoutlet port54 is connected by means of a pipe 57 with an air exhaustingdevice of any suitable character capable of creating a vacuum. Theplunger or piston valve 48 is provided with a coupling port 58, whichupon moving this valve into its innermost position, as shown in Fig. 3,will place the inlet and outlet ports of the pressure line incommunication with each other. Uponmoving this piston valve outwardlyinto its central position, as shown by dotted lines in Fig. 3, thecoupling port 58 thereof will establish connection. between the inletand outlet vent ports 51, 52 and upon moving this piston or plungerintoits outermost position, as shown by full lines in Fig. 1, thecoupling port 58 thereof will connect the'inlet and outlet ports 53, 54of the exhaust line.

When, therefore, the piston valve 48 connects the cylinder 39 with theair pressure line, the motor piston 38 will be pushed inwardly andproduce a clamping action on the bundles of shingles. Upon moving thepiston valve into its central position the cylin der 39 will be placedin communication with the atmosphere and thereby relieve and thepressure of the clamping jaw against the bundles in the cage, and bymoving the piston valve into its outermost position the cylinder 39 willbe placed in communication with the suction line for creating a vacuumin this cylinder and causing the piston 38 suflicient duration to to bewithdrawn from the bundles of shingles into its outermost position inwhich the jaw 37 clears the ath of the same, as shown by full lines inig. 1.

The dc ression of the piston valve 48 is produced y a handle 59 which issecured to the outer end of avalve stem 60 connecting the piston valvewith the handle and passing through a stufiing box 61 at the front ofthe valve'casing 46 and the outward movement of this piston valve isproduced by a spring 62 surrounding the valve stem and bearing at itsinner and against the stufling box 61 and its g uter end against thehandle 59, as shown in ig. 3. The depression of the valve 48 into itsinnet-most sition can be effected very easily and quickly by pressure ofthe hand against the handle 59, butthe backward, return or outwardmovement of the same is retarded by means of a. checking or retardingdevice whichpreferably consists of a check valve 63 arranged within apocket 64 on the lower end of'the valve casing 46 and adapted to closeinwardly against a valve seat 65 which con trols a retarding portleading to the inner or lower end of the valve bore 47. This check valveis yieldingly held against its seat by means of a spring 66 arrangedwithin the pocket 64 and interposed between the outer side of the valve63 and a screw cap67 applied to the lower end of the casing 46, this capbeing provided with an opening 68 whereby this p gceket communicates;with the atmosphere.

casing 46 of the controlling valve is held stationary in an suitablemanner, for in stance by a brac et 69 connecting the same with theadjacent hearing 29, as shown in on depressing the plunger valve 48 thecheck valve 63 opens freely and permits the air below the plunger toescape from the low-, er and of the bore'47, but during the upwardstroke of the plunger valve 48 the check valve 63'will en ge the seat 65and almost close the su cient leakage being permitted in this c eckvalve so that only a slow passage of air from the exterior of the casingwill be possible into the lower end of the valve bore 47 as the plungervalve rises, and thereby causing the upward or outward movement of thisplunger valve to be retarded. It follows from this construction thatafter the compressed air is admitted to the cylinder 39 for forcing thejaw 37 against the bundle of shingles and then removing the handpressure rom this plunger valve, that this air pressure will bemaintained on the jaw 37 for a short time, which is, however, of permitthe draining c after starting its rotation, to get under fllfl or normalspeed, and thereafter the coupling port of the plunger valve 48 duringits continued upward or. outward movement at aislpw rate will first cutofi' the compressed air suppl then connect the working end of the cyliner 39 with the atmosphere through the vent ports 51, 52, andthen connectthis end of the working cylinder with the exhaust ports 53, 54 forwithdrawing the clamping,

aw from the bundles of shingles. As a result of this slow release of theclamping mechanism from the bundles the latter will be reliably heldagainst radial displacement in the draining cage during the initial slowrotary movement of the latter when starting the drainingoperation, andwhen the cage has acquired a suflicient rotary speed so that the bundlestherein will be held by centrifugal force against one side only of thedraining cage, the bundles are released from the grip of the clampingdevice, thereby permitting the bundles to adjust themselvesautomatically to the inner surface of the cage in response to thecentrifugal force acting thereon and enabling them to spread out orrelax into a loose condition so that the excess liquid deposited thereonduring the dipping process will be able to escape therefrom with themaximum freedom and thus insure the most effective draining of thebundles and recovery of the greatest amount of the liquid with which thebundles have been treated.

After the draining cage has been rotated a sufficient length of time todrain the surplus liquid from the bundles of shingles and just beforethe power for turning the draining cage is cut off, the attendant pushesthe plunger valve 48 inwardly so as to again admit compressed air intothe working end of the motor cylinder 39 for the purpose of clamping orholding the bundles within the draining cage against displacement as therotary speed of the draining cage gradually slows up and the cagefinally comes to rest, thereby preventing the bundles from chuckingradially from one side of the cage to the other as the rotary speed ofthis cage is reduced below normal, thereby preventing the two'groups ofshingles in each bundle from being hammered or pushed in endwise, whereby the shortening of the bundle and possible breaking of the binders andscattering of the shingles is prevented.

The operation of this controlling valve is preferably so timed that theclamping action of the jaw 37 on the bundles is not released until afterthe rotary action of the draining cage ceases. Thereafter the slowreturn'ing plunger valve 48 under the action of the spring 62 willsuccessively cut off the air pressure from the working cylinder 39, thenconnect this cylinder with the vent to the atmosphere, and then connectthe same with the suction line 57 so as to withdraw the clamping jaw 37from the space within the cage, leaving the latter unobstructed andpermit the removal of the draining bundles from the cage and the loadingof a new batch of til bundles into the same without any interferencefrom the clamping mechanism.
